If you understood high grading you wouldn't have referenced high grading the gene pool in this post.
The only way we could high grade the gene pool is to not shoot bucks till they reach 4 1/2 and then take the best ones out. High grading before that age is a myth.
So you are, in effect, saying that what you call high grading will occur with or without our present AR's, meaning that your prior claim that AR causes high grading is therefore false. Once again,You cant have it both ways.
No, that is not true at all. Prior to ARs , the buck harvest consisted of a random sample of the entire legal buck population. With ARs we are selectively harvesting the best buck with the highest potential for antler development.
I am not citing my definition of high grading, I am citing Dr. Demarais's definition. You better reread his example of high grading a timber stand and maybe the light will go on.
